Abstract
The utility model discloses a double transmission device for a central shaft of a pendulum pulverizer used to grind powdered ores. The transmission device comprises at least two belt pulley transmission mechanisms which are evenly distributed around the central shaft of the pendulum pulverizer; in general, the transmission device adopts two belt pulley transmission mechanisms which are symmetrically arranged on both sides of the central shaft respectively; each belt pulley transmission mechanism is a commonly used two-level speed reduction transmission mechanism which comprises a first-level speed reduction driving belt pulley, a first-level speed reduction driven belt pulley, a second-level speed reduction driving belt pulley and a second-level speed reduction driven belt pulley; the second-level speed reduction driven belt pulley which is public is coaxially and fixedly connected with a shaft end on the bottom of the central shaft. Because the belt pulley transmission mechanisms are symmetrically arranged, lateral drawing forces of belts of the belt pulley transmission mechanisms on the central shaft are balanced, thereby eliminating the declining phenomenon of the central shaft, keeping the central shaft vertically rotating and reducing the abrasion of the central shaft.
Description
(1) technical field:
The utility model relates to a kind of transmission device of pendulum type ring roll pulverizer, is the central shaft dual transmission of pendulum type ring roll pulverizer specifically.
(2) background technique:
Pendulum type ring roll pulverizer is mainly used in milling to various breezes or other dry fragility article, the working principle of the pendulum type ring roll pulverizer centrifugal force that to be the horizontal grinding roller of dependence produce in the revolution running and on bull ring rotation roll material ground, grinding roller is hung from above on the plum blossom frame by cantilever, and the rotation of plum blossom frame is driven by vertical center axis.Central shaft is by the center pedestal of upper and lower bearing location and installation in relieving tool post, and the lower shaft end of central shaft is stretched in the support bottom, and is connected with transmission device, and with regard to present pendulum type ring roll pulverizer, the main kind of drive that drives the central shaft rotation has two kinds:
1, monolateral pulley drive system.
Central shaft is moving by the belt pulley frenulum by the motor that is positioned at a side, the central shaft bottom is subjected to the belt transmission radial pull of a direction, again because the suspension point of grinding roller is higher, central shaft is longer, causes central shaft generation deflection, makes the wearing and tearing aggravation of the opposite side at the stressed side in central shaft bottom, central shaft top during rotation, generally, central shaft was just changed because of concentrated wear in 1 year, had increased the weight of user's economic burden, caused stopping production because of device maintenance again.
2, speed reducer transmission system.
For avoiding the generation of above-mentioned situation, and adopt the speed reducer transmission system to replace monolateral pulley drive system, speed reducer is installed in the central shaft bottom, and the output shaft of speed reducer is connected with central shaft by (rubber) coupling.The speed reducer transmission system can guarantee that deflection does not take place central shaft; but cause the cost of whole pendulum type ring roll pulverizer to increase again because of its manufacture difficulty is relatively large, on the high side; and because of (rubber) coupling damages in use easily, cause the shutdown maintenance of pendulum type ring roll pulverizer, influence is produced.
(3) model utility content:
At the deficiency of above-mentioned traditional pendulum type ring roll pulverizer central shaft transmission device, the purpose of this utility model has provided a kind of pendulum type ring roll pulverizer central shaft dual transmission that cost is not high, can prevent the central shaft beat that increases.
Can realize the pendulum type ring roll pulverizer central shaft dual transmission of above-mentioned purpose, its contribution to prior art has been to improve the layout of pendulum type ring roll pulverizer central shaft transmission device, and its mentality of designing realizes by following structure:
The utility model pendulum type ring roll pulverizer central shaft dual transmission comprises driving central shaft pivoted pulley driving mechanism, the negative pulley wheel of pulley transmission mechanism is coaxial to be connected on the axle head of central shaft bottom, different is is the belt that the improves single pulley transmission mechanism side direction pulling force to central shaft, and be designed to more than two pulley transmission mechanism identical a plurality of at least, the drive pulley of a plurality of pulley transmission mechanisms is that the center evenly distributes around it with the negative pulley wheel on the central shaft, causes each pulley transmission mechanism that the radially belt pull of central shaft is in balance.
For making layout structure simple, described pulley transmission mechanism is general to adopt two, the drive pulley of each pulley transmission mechanism is symmetrically distributed in the negative pulley wheel both sides on the central shaft, and the power of each pulley transmission mechanism equals half that central shaft rotates total output.
According to the needs of reduction of speed velocity ratio, each pulley transmission mechanism can or be multistage reduction of speed driving mechanism for one-level reduction of speed driving mechanism.
Pulley transmission mechanism adopts the two-stage speed-down driving mechanism, and then adaptive surface is wider.
The two-stage speed-down driving mechanism that adopts comprises one-level reduction of speed drive pulley, one-level reduction of speed negative pulley wheel and two-stage speed-down drive pulley, two-stage speed-down negative pulley wheel, wherein the two-stage speed-down drive pulley is the drive pulley of preceding described pulley transmission mechanism, public one of two-stage speed-down negative pulley wheel, this public secondary negative pulley wheel are the preceding described coaxial negative pulley wheel that is connected on the axle head of central shaft bottom.
The secondary negative pulley wheel is connected with secondary drive pulley in two pulley transmission mechanisms respectively by two cover belts, interferes for avoiding two cover belts, and two overlap belts alternates respectively in public secondary negative pulley wheel race.
The beneficial effects of the utility model:
1, the utility model pendulum type ring roll pulverizer central shaft dual transmission symmetric arrangement pulley transmission mechanism, with the radially belt pull balance of pulley transmission mechanism to central shaft, eliminate the central shaft skewness, keep the vertical rotation of central shaft, reduce the wearing and tearing of central shaft.
2, the pulley transmission mechanism of setting up owing to symmetric arrangement less than the influence of adopting the speed reducer driving mechanism to the pendulum type ring roll pulverizer cost, thereby adopts pendulum type ring roll pulverizer cost performance of the present utility model higher to the influence of pendulum type ring roll pulverizer cost.
